Idina Menzel Sings "Let It Go" as the Bloomingdale's Holiday Windows Are Revealed

Idina Menzel is getting us in the seasonal spirit! The star helped unveil Bloomingdale's holiday windows in New York City last night by giving a rousing performance of selections from her new Holiday Wishes album along with the ever-popular "Let It Go" from Disney's hit movie Frozen (Menzel voiced Elsa in the animated flick). The event kicked off with a special opening performance by iLuminate, a dazzling show troupe that combines music, technology, and electrifying entertainers performing in light suits.

This year, the Bloomingdale's windows invite onlookers to get in on the excitement with an entirely interactive experience. The high-tech Big Apple–inspired displays include games featuring the Bloomingdale's holiday "Gift a Bow" mascot along with the opportunity to interact with the windows via social media using #bloomiesgreetings.
